IMPROED SGAFFOLl-)ING-BRAGKET.

tro ALL WHC/M 1T MAY eoNoERN:

Be it known tha-t I, JOHN S. WILSON, of Indianapolis, in the county of Marioman'd State of Indiana, have invented a new and 'useful Bracket for Scaiolding; and I do hereby declare that the following is a full, clear, and exact description thereof, reference'being had to the accompanying drawing, making part of this specification. v

' My invention. relates to mode of erecting and supporting the' seaolding or staging used by painters, builders, and others. having occasion to work upon the exterior of buildings, and' eonsistsin the employment of aA bracket of peculiar construction, adapted to'adjustment in' the window-openings, andivhich may also be supported; against the walls by meansof a brace resting on the ground, the boards or staging upon which the workmen stand'beinglaid upon andsupported by the horizontal arms of these brackets, which lare also susceptible of being put up withfacility and rapidity, at little cost, and with-out nailing topor otherwise marring tho building.

i .Figure 1 represents aside View of the bracket as adjusted inawindow-opening.

Figure 2 represents a. side view of the bracket, as supported against the wall by a brace from the ground.

Figure 3 is a front view of the bracket, y v 3 4 The bracket is usually made of Wood, and isicomposed of the pieces of scantling B, halved together, or the piece A mayhave-a tenon, which is insert-ed' inar mortise, in' pieeeB, and securely nailedor bolted thereto. These pieces are firmly braced by two thinner' pieces C, nailed or bolted to the pieces A B,`as Ashovnnbeng placed opposite each other. D are two other b race-*pi'eces'of the same thickness as the pieces 0, nailed or bolted to pieces A B,Anear the angle where they are joined, and'in such manner as to form a recess to receive the upper end of prop E, as shown. The pieces A, B,\and C are put together in such relation to each other as that the bottom projecting ends of pieces B C form 'a crotch that will 'stridc'the windo\r-sill, las shown in tig.'1, and so that the arm Awill project at a right angle to tho wall of the building, `and the upper projecting end otpiecc B will rest against the inner edge of the window-frame at the to'p,was shown'. -The upper end of piece B may project above the arm A any practicable height, to adapt the bracket to various heights of window-openings.

It will alsobe'seen-that the pieces A B C are formed and put together lin such a manner that, when placed against a .wall,as shown in g. 2,.tl1e -arm A will stand at a right angle to the wall, and this lquality of the bracket, whereby it is susceptible of. adjustment, either-in afwindow-opening vor to the wall, depends upon the form, construction, and relation of the pieces A, B, and C to each other, as clearly shown in the drawing.

These brackets may be mounted one above another', as indicated by the dotted lines in iig. 1, the foot of.

prop E resting against a block, I, nailed to the outer end of arm A, and thusithe staging vF'niay be supported at any desired height. The prop E should be of the same thicknessA as the pieces A B, so aste hold the bracket rmly. i v I y Having thus-,fully described .myjnventiom whatl claim therein as new, and 4desire to secureby Letters Patent, is#- l n The bracket for sca'olding, composed of' the-elements A, 13,0, 'and D, constructed and arranged substantially as v'and for'the purpose set forth. i
